摘要: 【目的】 了解昆山地区0~3岁儿童超声骨密度现状,为儿童骨强度不足早期干预提供依据。 【方法】 对813名排除影响骨代谢性疾病的0~3岁儿童,用超声骨密度仪测定左胫骨中段骨密度,根据骨密度Z值的评分数分成正常、轻度、中度以及重度骨强度不足。 【结果】 骨强度不足检出率女童( 49.46%) 高于男童( 34.47%),不同性别儿童骨强度不足率差异有统计学意义(χ2=16.82,P<0.01),而骨密度值差异无统计学意义(t=0.41,P>0.05);骨密度值随年龄增长而增加,以42 d(50.91%)、3月龄(62.50%)儿童骨强度不足检出率较高,不同月龄儿童骨强度不足率差异有统计学意义(χ2= 28.36,P<0.01);不同地区儿童骨密度值差异有统计学意义(t=3.14,P<0.05),而骨强度不足检出率差异无统计学意义(χ2= 3.883,P>0.05);不同身高评价儿童骨密度值差异有统计学意义(F=11.92,P<0.01),以身高评价为上和中上,体重评价为上和中上儿童骨强度不足检出率较高,不同身高评价儿童骨强度不足率差异有统计学意义(χ2=11.02,P<0.05),而不同体重评价儿童骨强度不足率差异无统计学意义(χ2=6.68,P>0.05)。 【结论】 儿童骨强度不足应引起高度重视,尤其是12月龄以下儿童骨强度不足的问题。

Abstract: 【Objective】 To examine the status of the ultrasonic bone mineral density(BMD) of 0~3 years old children in Kunshan,and to provide evidence for early bone strength deficiency intervention. 【Methods】 The left tibia BMD of 813 children aged 0~3 years old no including who had bone metabolic illnesses were measured by quantitative ultrasound.The patients were divided into normal,mild,medium and severe groups of bone strength deficiency according to Z-score of BMD. 【Results】 The incidence rate of bone strength deficiency in girls(49.46%)was significantly higher than that in boys(34.47%),(χ2=16.82,P<0.01),while the BMD value had no statistical significance(t=0.41,P>0.05) between boys and girls.The BMD value increased with the age increase.The incidence rate of bone strength deficiency in children aged 42 days (50.91%) and 3 months (62.50%) was higher than the others,there was statistical significance(χ2= 28.36,P<0.01).The difference of BMD value had statistical significance (t=3.14,P<0.05)between city and town,while the incidence rate had no statistical significance(χ2=3.883,P>0.05).The difference of BMD value had statistical significance(F=11.92,P<0.01) among different grades of height evaluation.The incidence rate of bone strength deficiency in children whose height (weight) evaluation was upper or higher-middle was higher than the others.There was statistical significance(χ2=11.02,P<0.05) among different grades of height evaluation,while no statistical significance (χ2=6.68,P>0.05)among different grades of weight evaluation. 【Conclusion】 Children bone strength deficiency should be pay more attention,especially for those under 12 months.
